HAVING Clause


The HAVING clause is used to filter grouped data.

It works with GROUP BY and aggregate functions.

HAVING is applied after grouping is completed.

WHERE cannot be used with aggregate results.

HAVING is specifically designed to filter grouped data.

This makes HAVING different from WHERE.

HAVING is used when conditions depend on aggregate values.

It allows filtering based on SUM, COUNT, or AVG results.

This is common in reports and analytics.

HAVING is written after GROUP BY.

It filters groups, not individual rows.

This is an important SQL concept.

HAVING is widely used in dashboards and reports.

It helps analyze large datasets efficiently.

Understanding HAVING is essential for advanced SQL queries.
